Before his capture, warrants had been issued for 23-year-old Lawson on three counts of murder and one count of aggravated murder, according to Lawrence County Sheriff Jeffrey Lawless.

The adults' bodies were discovered Wednesday night and a missing-child alert was issued for Devin Holston. His remains had been hidden in the trailer and weren’t discovered until Thursday, officials said.

“Devin was widely liked by all the staff and students,” Wes Hairston, superintendent of Rock Creek Local Schools, told The Columbus Dispatch. “It’s a tragedy that someone this young would perish by someone in a senseless act of hate or violence."

Lawson is reportedly a cousin of at least one victim. A fifth person, who arrived home from work at the rural home and discovered the bodies, was stabbed and taken to a West Virginia hospital, cops said.
